Definitions

  • the present invention relates generally to urinary flow control valves, and, more particularly, to adapting such valves to temporarily permit continuous fluid flow.
  • Urinary control devices such as urinary catheters
  • Two types of urinary catheters have been developed to assist in this need and can be considered as comprising either a continuous drainage catheter or a valved urinary catheter.
  • Continuous drainage catheters are used when continuous drainage of an individual's bladder into a collection bag or reservoir is desired, such as during or after surgery or when mobility of the individual is not a primary concern.
  • Valved urinary catheters are used to retain urine within the bladder until it is desired to void the bladder through actuation of a normally-closed urinary flow control valve located within or external to the urethra.
  • the urinary valves of such devices typically include a valve housing with flexible, resilient walls that contain therewithin the actual valve element.
  • the housing walls When the housing walls are squeezed either directly when the valve housing is outside of the urethra, or through palpitation through the penis, for example, when the valve housing is in the urethra, the walls flex and cause the valve therein to deform and open for release of urine. Release of the squeezing pressure on the housing walls allows the valve to return to its original, closed state.
  • Valved urinary catheters are used predominantly with mobile individuals so as to provide a urinary flow control device that is not discernable by others and that is compatible with the individual's normal daily activities.
  • the valved urinary catheter there are times when it is convenient for the valved urinary catheter to be temporarily configured to allow continuous flow. With such a capability, the benefits of both types of catheters can be achieved without requiring an individual to undergo removal of one type of catheter and insertion of the other.
  • Previous attempts at addressing this problem involved inserting a hollow tube, roughly the size of the inside of the catheter tube, into the catheter outlet far enough to grossly deflect the valve and to cause the valve to open. The tube would form a fluid-tight seal between the walls of the catheter outlet and the outer surface of the hollow tube. As a result, urine can continuously flow through the inside of the hollow tube.
  • the tube has the tendency to greatly deform, and thereby damage, the valve during use, especially prolonged use. As a consequence, the valve may no longer be able to seal after the hollow tube is removed, leading to unacceptable leakage. Further, the tube is held in place only by frictional engagement which can often work loose resulting in leakage and/or failure of the valve to be held open.
  • the present invention provides an adaptor which temporarily transforms a valved urinary catheter into one that permits continuous fluid flow by deforming the valve in a manner similar to prior hollow tubes, but without the shortcomings thereof.
  • the adaptor includes a tube which sealingly engages with the catheter outlet and also includes an actuator member having a tip sized to allow urine to flow therearound and into the tube when the actuator member extends against the downstream side of the valve to deformably open same.
  • the actuator member is of a smaller diameter than the tube, and therefore does not greatly deform the valve, thereby overcoming one of the shortcomings of the use of prior hollow tubes as the structure for both fluid flow and for deforming and opening the valve.
  • a releasable clip is advantageously associated with the tube, the releasable clip adapted to engage with an exterior surface of the catheter outlet, so as to hold the adaptor in place with the member holding the valve body open for continuous flow.
  • the clip may squeeze down on the outside of the catheter outlet to help maintain the seal with the tube of the adaptor.
  • the clip may include a safety feature that prevents it from being overly compressed against the catheter outlet.
  • the clip may be designed to engage an exterior surface of the catheter only when the adaptor is fully inserted.
  • the clip may include a protuberance that contacts an external portion of the catheter, valve housing, or discharge tube so as to prevent the adaptor from being over-inserted into the catheter.
  • the actuator member is advantageously solid, such that all urine flow is around the member and into the tube.
  • increased fluid flow may be obtained by using a hollow actuator member, such that urine flows both around and through the member and into the tube.
  • the member may advantageously be a pin or rod.
  • the valve is a duckbill-like valve with an openable slit therein
  • the actuating member has a diameter smaller than the length of the slit such that when inserted against the valve, the slit will open to provide fluid flow regions between the actuating member and the walls of the duckbill valve slit.
  • FIG. 1 is a cross-sectional view of an adaptor in accordance with principles of the present invention as inserted within the outlet of a catheter.
  • FIG. 2 is a perspective view of the adaptor of FIG. 1 .
  • FIG. 3 is a front plan view of the tube and probe of the adaptor of FIG. 2 .
  • FIGS. 4A and 4B are front views of a duckbill valve in a closed position and an open position, respectively for purposes of explaining the principles of the present invention.
  • urinary catheter 2 includes a urine outlet tube 4 downstream of valve housing 5 and communicating with the downstream side 6 of valve 3 within valve housing 5 .
  • the upstream side 7 of valve 3 communicates through a lumen 8 along catheter body 9 within the urethra 10 of an individual so as to communicate with or into a bladder 11 of the individual (not shown).
  • Catheter 2 may also include one or more further valved lumens 12 used to inflate one or more balloons 13 or the like for holding catheter 2 within the individual's urethra 10 .
  • Catheter 2 as shown in FIG. 1 has the valve housing 5 and outlet tube 4 extending outside the urethra 10 , although a catheter with the valve within the urethra could also be employed.
  • valve 3 is of the type that is normally closed, but opens in response to force or pressure externally applied to valve body 5 such as to deform valve 3 to thereby open same to permit the individual to void.
  • adaptor 20 In order to temporarily transform valved catheter 2 into a catheter that permits continuous urine flow therethrough, adaptor 20 is provided. With reference to FIGS. 1 and 2 , adaptor 20 advantageously includes a hollow tube 22 which fits matingly within outlet tube 4 of catheter 2 . Extending from upstream end 23 of hollow tube 22 is an actuator member 24 which is sized for urine to flow therearound and into hollow tube 22 , such as through end 23 thereof. Instead of having end 23 of tube impact or otherwise deform valve 3 , as was conventional of prior hollow tube approaches, the projecting actuator member 24 protrudes into the valve 3 at the downstream side 6 thereof. Actuator member 24 may be a rod as seen in the Figures which has a diameter substantially smaller than the outer diameter of tube 22 . This substantially smaller diameter reduces the deformation effect on the valve 3 such that after actuator member 24 is removed, valve 3 will reliably reclose without leakage.
  • Catheter 2 allows the individual great flexibility in controlling when and how to discharge urine. However, if the individual is to undergo surgery or, for other reasons, becomes immobile, then the normally-closed valve 3 is not entirely beneficial. In those instances, a catheter that allows continuous flow of the urine is more convenient for the individual. Instead of requiring the individual to undergo repeated removal and insertions of various catheters, the adaptor 20 just described may be used to temporarily convert the valved catheter 2 into a continuous flow catheter.
  • actuator member 24 may be associated with tube 22 such as by being held to the actuator member 24 so as to be positioned to extend beyond the tube 22 .
  • supporting struts 26 may extend from the inner wall 28 of tube 22 to hold actuator member 24 with a downstream end at or just within upstream end 23 of tube 22 .
  • Struts 26 also define large openings 30 through which urine may flow as it passes around actuator member 24 and into tube 22 , so as to communicate through tube 22 and out of adaptor 20 .
  • the outlet or downstream end 31 of tube 22 may be connected, either permanently or selectively, to a drainage tube 33 , which couples to a drainage bag or the like (not shown) for collection and subsequent disposal or other handling, of the urine from the individual.
  • the upstream end 23 of the tube 22 has an outer diameter that is smaller than, but substantially similar to, the inside diameter of the outlet tube 4 so that the adaptor 20 can slide into outlet tube 4 .
  • the adaptor tube 22 is substantially cylindrical at its upstream portion and becomes conical so as to taper outwardly towards its downstream portion. This shape helps create a friction fitting when engaging the inside of the outlet tube 4 . In this position, the urine cannot flow between the inside of the outlet tube 4 and the outside of the adaptor tube 22 ; but, instead, flows within the adaptor tube 22 .
  • the outlet tube 4 is depicted as having a circular cross-section and the adaptor is shaped accordingly to complement that shape.
  • the outlet of the catheter need not be a tube, but an opening, and in any event may have a different cross-sectional profile, such as triangular or some other shape, in which case the adaptor tube 22 would be shaped accordingly so as to create the desired friction fitting.
  • the actuator member 24 engages the downstream side of the valve 3 so as to deflect the valve 3 into an open position such that urine flows through the valve and around the actuator member 24 . Accordingly, fluid is able to flow through the valve 3 but the valve 3 is not grossly deformed or damaged by the tube 22 .
  • the particular adaptor 20 depicted in FIGS. 1 and 2 includes additional features that enhance its ability to remain securely attached to the catheter 2 .
  • a releasable clip consists of two resilient arms 30 , 32 that fixedly snap together by engaging the detent 34 of the arm 30 with the latch 36 of the arm 32 .
  • one pinch rib 37 pinches down towards the tube 22 and the other pinch rib 38 pinches up towards the tube 22 .
  • the pinch ribs 37 , 38 act to hold the outlet tube 4 firmly against the adaptor tube 22 .
  • the pinch rib 37 is advantageously angled toward one end, such as the downstream end, and is made more resilient (either by selection of materials or due to its thinness) than the other portions so as to permit greater deflection of this pinch rib 37 .
  • pinch rib 37 operates with a spring-like effect that prevents crushing the outlet tube 4 and also applies a more reliable force on tube 4 .
  • they can be shaped so that their profile matches the outside curvature of the tube 22 .
  • the arm 30 and detent 34 extend into a safety rib portion 35 .
  • This safety rib 35 acts as a mechanical stop that prevents the arm 30 from being overly compressed towards the tube 22 . As a result, over-flexing of the pinch rib 37 , and damage thereto and/or to outlet tube 4 , is prevented.
  • urine communicates from the bladder 11 to the valve 3 .
  • the actuator member 24 engages the valve 3 from the downstream side to cause the valve 3 to open, such as by deflecting the valve walls 15 .
  • Urine flows through the now-open valve 3 , over the actuator member 24 and towards the inside the tube 22 passing through the openings 30 that are at the base of the actuator member 24 (see FIG. 3 ). The urine can then travel through the hollow tube 22 of the adaptor 20 towards the downstream end 31 .
  • the resilient arms 30 , 32 can be sized and shaped to assist in positioning the adaptor 20 .
  • the edge of the arm 32 below the latch 36 acts as a protuberance which butts up in contact with the outside of the valve body 5 of catheter 2 as at region 50 .
  • This contact between the adaptor 20 and the catheter 2 acts as a positive stop and will not permit the adaptor 20 to be over-inserted into the catheter 2 and valve 3 .
  • Over insertion can increase the deflection, or deformation, of the valve 3 or, in the extreme, lead to damage of the valve 3 .
  • the individual By positioning the pinch ribs 37 , 38 so that they apply their pinching effect downstream along the tube 22 , the individual is given a visual indication that the adaptor 20 may be under-inserted because the pinch ribs 37 , 38 will not engage any portion of the outlet tube 4 if the adaptor 20 is not inserted far enough.
  • the shape and size of the resilient arms 30 , 32 and their accompanying features, such as the pinch ribs 37 , 38 assist the individual in properly inserting the adaptor 20 within the catheter 2 .
  • FIG. 2 depicts an embodiment of the adaptor 20 that has all features integrally formed, such as would result from thermoplastic injection molding, other embodiments of the present invention contemplate two or more separate pieces assembled together to form the adaptor 20 .
  • the resilient arms 30 , 32 can be formed separately from an assembly of the actuator member 24 , tube 22 , and support arms 60 , 61 . These two assemblies could then be connected together.
  • the resilient arms 30 , 32 , the support arms 60 , 61 , and a downstream portion 52 of the tube 22 could be formed integrally and attached to an assembly of the actuator member 24 , and the upstream portion of the tube 22 .
  • the adaptor 20 is advantageously molded from Profax PF511 Polypropylene thermoplastic; however, other thermoplastic materials can be used such as HDPE, Acetyl, or other medical grade plastic.
  • the resilient arms 30 , 32 have respective openings 62 and 64 .
  • the opening 62 accommodates the downstream end 31 of the adaptor 20 and facilitates attaching a urine discharge device.
  • the opening 64 is near the upstream side of the adaptor 20 and allows the tube 22 to fit inside the outlet tube 4 of the catheter 2 without interfering. Additional features, such as the ribs 66 , are also shown in FIG. 2 and can provide tactile assistance to an individual using the adaptor 20 .
  • Exemplary embodiments of the present invention are particularly adapted to work with catheters and valves, such as double duckbill valves, that are described in the present Assignee's co-pending patent application Ser. No. 10/000,276, filed Nov. 2, 2001, the disclosure of which is incorporated herein in its entirety by reference.
  • the adaptor 20 herein described can operate with any valved urinary catheter in which the valve can be deformed or deflected from the downstream side so as to open.
  • FIGS. 4A and 4B illustrate the interaction of the actuator member 24 with such a valve 3 when the adaptor 20 is inserted into the catheter 2 . Both of these figures depict the valve 3 as viewed from the bladder end looking downstream towards the outlet tube 4 .
  • the valve 3 such as a double duckbill valve, is shown in its closed position in FIG. 4A .
  • the slit 70 is closed and, in this position, can withstand typical urinary fluid pressures without leaking.
  • the actuator member 24 engages a portion of the valve 3 from its downstream end to displace the walls 15 so as to cause the slit 70 of the valve 3 to open.
  • Actuator member need not project through the slit 70 to open the valve 3 but may advantageously do so to define fluid flow regions 72 , 74 on each side of the actuator member 24 .
  • the major axis 22 ′ of tube 22 , the major axis 24 ′ of actuator member 24 , and centerline 3 ′ of valve 3 are all aligned or coaxial. They need not be, however.
  • the major axis 24 ′ of actuator member 24 could be offset from the major axis 22 ′ of tube 22 .
  • the axes and centerline would be generally aligned so as to extend generally parallel to one another. Actuator member 24 wold thus be offset from the center of the valve 3 and the slit 70 so that only a single fluid flow region is created as the slit 70 opens.
  • any urine on the upstream side of the valve 3 will flow through the fluid flow regions 72 , 74 towards and into the tube 22 without requiring manipulation of the valve housing 5 .
  • the actuator member 24 of the adaptor 20 does not form a complete sealing relationship with the walls 15 of the valve 3 ; instead, fluid flows over and around the outside of the actuator member 24 (and also through it if it is hollow).
  • urine will flow through the openings 30 , through the tube 22 of the adaptor 20 , and out the downstream end 31 . In this manner, continuous fluid flow can still be achieved while avoiding the extensive deformation of the valve 3 that results from use of only friction fit tubes to open the valve 3 .
  • FIG. 1 depicts one alternative in which the actuator member 24 extends entirely through or almost entirely through the walls 15 of the valve 3 and it will be appreciated that actuator member 24 may push on the valve walls 15 .
  • the actuator member 24 pushes into the valve 3 at least half the thickness of the valve walls 15 , then a fluid path through the valve 3 is formed.
  • a held-open urine flow path is created whether the actuator member 24 extends through the valve 3 or merely deforms the valve walls 15 from the downstream side.
  • the slit 70 of the duckbill valve 3 may have a length of approximately 0.180 inches. Knowing the outside diameter of the actuator member 24 will permit calculation of the area of regions 72 , 74 . If the actuator member 24 has a diameter of 0.055 inches, then each region 72 , 74 will have an area of approximately 0.0014 square inches for a total of 0.0028 square inches. Thus, an actuator member 24 having a cross-sectional area of 0.0024 square inches can be used to create a larger, relative fluid path of 0.0028 square inches through the valve 3 .
  • the actuator member 24 may be hollow to permit fluid flow though its center as well.
  • the actuator member 24 may have an inner diameter (not shown) of 0.035 inches thereby adding another 0.001 square inches of area through which urine may flow.
  • embodiments of the present adaptor 20 can be used to temporarily transform a valved urinary catheter 2 into one that permits continuous fluid flow.
  • the adaptor 20 is inserted within the discharge tube 4 of the catheter 2 so that an actuator portion, or tip, 24 of the adaptor 20 holds the catheter valve 3 in an open position.
  • the embodiments of the present invention described herein minimize the deflection and deformation of the valve 3 caused by the actuator portion 24 .
  • the actuator portion 24 deflects the valve 3 in such a manner as to create a fluid flow path in-between the valve 3 and the actuator portion 24 .
  • the adaptor 20 can be sized and shaped to work with a catheter in which the valve and valve housing are located within the urethra as well.
  • the actuator portion such as the actuator member 24
  • the upstream tip 25 of the actuator member 24 is advantageously hemispherical in shape although it could have other shapes.
  • the actuator member 24 is shown as rod-shaped with a circular cross-section, other rod-shapes are possible such as triangular, oval, and square cross-sections.
  • similar results can be attained by other, alternative attaching structures or by tapering the tube 22 to a narrow tip in the upstream direction to engage the valve 3 such that the tip of the tube 22 remains smaller in diameter than both the downstream portion of the tube 22 and the outlet tube 4 .
  • Urine flows around the outside of the narrow tip as before and enters the tube 22 downstream of the valve 3 , for example, through an aperture or other opening (not shown) located downstream of the valve 3 and on the periphery of the narrow tip.
  • the tube 22 can be sized to engage over the outlet tube 4 rather than within the tube 4 .
  • the actuator member 24 does not need to project past the upstream end 23 of the tube 22 .
  • the pinch ribs 37 and 38 may have different shapes and features such as teeth, spikes or other pinning-elements that help secure the adaptor 20 to the catheter 2 .
